Watch and share: What is DSD audio? Video explanation

DSD (Direct Stream Digital) is a one-bit audio format for high-resolution music. The format is based on sigma-delta modulation. Read details about DSD >

Music in DSD format may be stored in DSF and DFF files (.dsf and .dff file extensions respectively). Both DFF and DSF are DSD files.

I.e. DSD files is a common term, that includes both DFF and DSF audio files.

DSD versus DSF versus DFF files

However, besides these kinds of files, SACD ISO (.iso extension, 1-bit audio ISO) is DSD file too. SACD ISO contains text metadata, that may be extracted during SACD ISO to DSD conversion.

DSF and DFF files are able to contains binary identical audio content.

In .DFF audio content may be losslessly compressed. But it does not impact sound quality.

Sound quality for both file formats is defined by:

recording, mixing, postproduction/mastering quality;
conversion quality (read below);
playback quality (read below).

DSD vs PCM

Sometimes one-bit DSD is considered a more qualitative alternative for multi-bit PCM. However, it is not a simple matter, that is defined by implementation. Read more:

DSD converters

All DSD files (DSF, DFF, ISO) may be converted to another DSD format without losses. Such conversion should not alter sample rate and apply any processing ("bit-perfect").

DSD conversion

DSD resampling and other processing (even elementary gain changing) lose quality, comparable with PCM resampling. However, it is not a big matter for pro-audio processing.

DSD playback may be implemented two ways:

Convert to PCM and playback at PCM DAC (digital-to-analog converter),
Playback directly with DSD DAC.

In general, the second option is preferable. But real result depends on hardware and software implementation.

DSF vs DFF for players

Playback sound quality is the same for both DFF and DSF.

DFF file doesn't support music metadata (song name, album, performer, artwork) standard way. However, the metadata may be stored in ID3 format in DFF file's chunk (internal data block). For access to the metadata, DFF file player must be able to recognize ID3-chunks.

DSF specification supports the metadata. DSF audio player may have issues with artwork format, size and resolution.

To playback multichannel music at a stereo DSD player, the music sould be downmixed into 2.0 "on fly". Sound quality of downmixing is implementation matter. To save hard disk space, you can pre-downmix music.
